Hi,

Under some conditions TextBlock's text wrapping in SL2B1 makes text completely disappear from the TextBlock.  My simple demo app reproduces the problem 100% of the time.

The demo app, problem description and source code are here:
http://www.alancobb.com/pub/SL2/SL2B1_Bugs/TextBlockWrapping/ProblemDescription.htm

Addendum:
The problem seems to result when a TextBlock wraps at a point between two Runs.
A work-around is to only have one Run per TextBlock.  The disadvantage is you can
only use one text style (properties of Run) per TextBlock.

Is this a known issue?  Any suggested work-arounds?

Thanks,

Alan,

I have also run into some strange TextBlock wrapping issues when I have TextBlocks inside of a StackPanel.  It seems that for some wide TextBlocks, the TextBlock wraps around to the next row...even when an explicit width is set along with NoWrap.  I was able to work around the issue by switching the container control from a StackPanel to a Grid.  I don't know if this helps you out any, but I thought I would mention my issue as well.

Hi Page,

Interesting.  Unfortunately, adding a StackPanel or Grid around my
TextBlock does not help my particular wrapping issue.

I reduced my repro-demo to the following XAML.  As you resize 
the browser window horizontally, when wrapping has to take place 
between the two Runs "... a a a" and "b", all the text "disappears" from
the TextBlock.
